Description

[Detailed description of the invention] The present invention aims to provide a device that can easily short-circuit circuits during testing, adjustment, etc. regarding the configuration of printed circuit boards used in television receivers, etc. .

In television receivers, for example, when adjusting the white balance, it is necessary to short the oscillation output of the vertical deflection circuit to ground to stop vertical deflection, and for this purpose conventionally a switch called a service switch, Pin and plug shorting means have been used.

However, such conventional means have the disadvantage that additional switches, pins, plugs, etc. are required in view of the fact that they are used only during adjustment, resulting in high costs.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a low-cost device that can easily short-circuit a circuit by eliminating such conventional drawbacks.

An embodiment of the present invention will be described below with reference to the drawings.

In this device, as shown in FIGS. 1 and 2, a rectangular through hole 2 is provided in a printed circuit board 1, and two bare conducting wires 3a and 3b such as jumper wires are attached to the printed circuit board 1.

At this time, one end of each of the bare conductive wires 3a and 3b is folded in its tip so as to reach the inner wall surface of the opposite side of the through hole 2, and the other end of each is inserted into the printed circuit board 1 and inserted into the printed circuit board on the back side. 4a and 4b are connected with solder 5a and 5b.

The bare conductors 3 a and 3 b are configured to be short-circuited via the conductor 6 when the conductor 6 is inserted into the through hole 2 .

To attach the bare conductive wires 3 a and 3 b to the printed circuit board 1, first, as shown in FIG. Both ends are inserted and the respective ends are soldered to printed circuit boards 4 a and 4 b that constitute separate circuits.

Next, as shown in FIG. 3B, the central part of the bare conductor 3 is cut with nippers or the like to separate it into two bare conductors 3a and 3b, and then a jig 7 with a sharpened tip is used as shown in FIG. 3C. The printed circuit board 1
It is preferable to press fit into the through hole 2 from the upper surface side of the wire and fold the tips of each of the bare conductive wires 3a and 3b into the inner wall surface of the through hole 2.

At this time, if the jig 8 is applied to the back side of the printed circuit board 1, there is no risk that the printed circuit board 1 will be damaged.

In this way, the bare conductors 3a and 3b are inserted into the through hole 2 of the printed circuit board 1.
By using this device in which the ends of each wire are folded in, when short-circuiting the circuit to which these bare conductors 3a and 3b are connected, as shown in FIG. By simply inserting the conductor 6 into the through hole 2, the conductor 6 comes into contact with the bare conductor wires 3a and 3b to short-circuit the circuit, and by subsequently pulling out the conductor 6, the circuit can be returned to the open state.

Therefore, the circuit can be easily shorted by using only one bare conductor without using switches, pins, plugs, etc., and an extremely low-cost device can be obtained.

As described above, according to the present invention, the tips of the first and second bare conductors are folded into the opposing inner wall surfaces of a through hole provided in a printed circuit board, and a conductor is inserted into the through hole. Since the first and second bare conductors are configured to be short-circuited by the conductor, when short-circuiting the circuit connected to the other ends of the first and second bare conductors, a driver is used. All you have to do is insert a conductor like the tip of the
All that needs to be installed is the first and second bare conductors, and there is no need to use switches, pins, or plugs as in the past, and the device can be constructed at low cost.

Moreover, the first and second bare conductive wires can be obtained by cutting and bending one U-shaped bare conductor, so there is no need to prepare two bare conductors from the beginning. Therefore, it can be easily installed, and an extremely practical device can be obtained.
